嵌入式启动jetty

由于jetty8以上版本已经抛弃JDK1.6，公司统一开发JDK又一直不升级，所以我们使用jetty8

jetty.properties，依据项目结构自行修改

#jetty部署端口
jetty.port=8080
#jetty部署上下文
jetty.contextPath=/webapp
#资源路径,开发模式下默认为./src/main/webapp,也可设置绝对路径
jetty.resourceBase=./src/main/webapp
#web.xml路径,开发模式下默认为./src/main/webapp/WEB-INF/web.xml,也可设置绝对路径
jetty.descriptor=./src/main/webapp/WEB-INF/web.xml

DevStart.java，启动类，run main()

package com.nihaorz.start;

import org.eclipse.jetty.server.Request;
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.server.handler.AbstractHandler;
import org.eclipse.jetty.webapp.WebAppContext;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.Properties;

public class DevStart extends AbstractHandler {

    @Override
    public void handle(String s, Request request, HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws IOException, ServletException {

    }

    public static void main(String[] args) throws Exception {
        Properties prop = new Properties();
        prop.load(DevStart.class.getResourceAsStream("/config/jetty.properties"));
        WebAppContext context = new WebAppContext();
        // 设置端口
        Server server = new Server(Integer.parseInt(prop.getProperty("jetty.port")));
        // 设置部署上下文
        context.setContextPath(prop.getProperty("jetty.contextPath"));
        // 设置基础资源路径
        context.setResourceBase(prop.getProperty("jetty.resourceBase"));
        // 设置web.xml
        context.setDescriptor(prop.getProperty("jetty.descriptor"));
        context.setParentLoaderPriority(true);
        server.setHandler(context);
        server.start();
        server.join();
    }
